I have thought that this phenomana may be real for years . I call it the "quantiztion grid". An analog waveform can change direction or cross the zero line at an infinite number of locations. Sampling and Quantization create a grid to which features of the waveform are statistically constrained. Increasing the sample rate at a fixed bandwidth inreases the quantization grid density. Whether it is perceivable is what is in question. This experiment may have proved it. I will give some thought to a simillar experiment that forum members can do for themselves and start a new topic on it.

What would be the point? We have established that low level signals can be severely distorted by quantization, and that a nominal application of dither removes much, but not all, of that distortion. What more do you want to know?

None. I don't think KMD fully grasps the implications of the questions that they are asking.

It removes all the audible distortion.

True, there's still a visible relationship between the original signal, and the dither+quantisation - i.e. if you subtract the 8-bit version from the 16-bit version, you can see the difference isn't purely uncorrelated noise...
